Key takeaway
Klaviyo is a data-driven email and SMS platform built around e-commerce event triggers — abandoned cart, post-purchase, browse abandonment. mailtani is a focused email tool built for founders and indie hackers who want to own their infrastructure and pay once.
- Pricing model: per-contact monthly vs mailtani's €89 one-time
- At 10k contacts: €1,800/year on Klaviyo vs €89 total, forever
- Klaviyo includes SMS marketing and deep e-commerce event triggers — mailtani does email only, but better
- mailtani suits founders and small SaaS teams; Klaviyo suits e-commerce stores that need cart triggers and purchase data
Klaviyo is exceptional if you run an e-commerce store. If you don't, you're paying e-commerce prices for infrastructure architected around Shopify triggers you'll never use.
- Per-contact pricing that escalates sharply — €1,800/year at just 10k contacts
- Built for Shopify/WooCommerce — SaaS founders pay for e-commerce infrastructure they don't need
- No BYOS: locked to Klaviyo's shared infrastructure at every tier
- No email warmup or inbox rotation available
- Free plan capped at 250 contacts — barely useful for testing

What Is Klaviyo?
The e-commerce email powerhouse — built for Shopify stores, priced like enterprise software.
Klaviyo built its name on e-commerce email — tight Shopify and WooCommerce integrations, abandoned cart flows, post-purchase sequences triggered by real purchase data, predictive analytics for customer lifetime value. For online stores doing serious volume, it is a genuinely powerful tool with no real peer in the e-commerce email space.
The pricing is aggressive regardless of plan: 1,000 contacts costs €45/month, 10,000 contacts costs €150/month (€1,800/year), and 50,000 contacts pushes to €720/month (€8,640/year). Every time your list grows, the invoice grows with it — and unlike some platforms, there's no flat fee option.
What Is mailtani?
A one-time purchase email platform for founders, indie hackers, and small SaaS teams.
The core problem for most founders is target mismatch. Klaviyo's entire architecture — its triggers, segmentation model, analytics, and pricing — is built around e-commerce events. If you're a SaaS founder sending drip sequences, or an indie hacker building an email list, you're paying for abandoned cart infrastructure you'll never configure.
mailtani focuses on what founders and marketers actually need: sequences, broadcasts, contact management, warmup, and inbox rotation. At €89 one-time, you save over €1,600 in year one compared to Klaviyo at 10k contacts. Bring your own AWS SES account and your per-email cost drops to approximately $0.10 per 1,000 sends.

Why Users Switch from Klaviyo
The common reasons teams move on.
- You're paying e-commerce prices for a SaaS email list: Klaviyo's per-contact pricing is justified when you're monetising cart abandonment and post-purchase flows on a Shopify store. For a SaaS founder or indie hacker sending newsletters and drip sequences, it's paying a premium for infrastructure you don't need — and that premium compounds every month.
- The bill climbs every time your list grows: At 1k contacts you pay €45/month. At 10k contacts you pay €150/month. At 50k contacts you pay €720/month. Klaviyo's pricing is explicitly designed to grow with your audience — which means every subscriber you earn costs you more every month going forward.
- No bring-your-own SMTP at any tier: Klaviyo sends through its own shared infrastructure regardless of how much you pay. You cannot connect AWS SES or Resend. Your IP reputation is pooled with other Klaviyo customers and you have no lever to pull if deliverability drops.
- No warmup or inbox rotation built in: Klaviyo has no email warmup or inbox rotation tools. If you're launching a new domain or recovering from inbox placement issues, you're solving that problem entirely outside the platform — with separate tools at additional cost.
- The free plan is unusable for real work: Klaviyo's free plan allows 250 contacts and 500 email sends per month. That's barely enough to verify the platform works, let alone test a real onboarding sequence or broadcast. Paid tiers kick in almost immediately for anyone with a real list.

What You Get With mailtani
The features founders and indie hackers actually use — on your own infrastructure, for a one-time payment.
Bring Your Own SMTP
Connect your own AWS SES, Resend, or Mailtrap account and send at infrastructure cost. Your sending reputation is entirely yours — not pooled with other users on shared IPs.
Email Warmup
Automatically ramps up your sending volume over 3–6 weeks, building genuine sender reputation with Gmail and Outlook. Set it once — mailtani handles the daily schedule without a separate tool.
Inbox Rotation
Distribute sends across multiple inboxes automatically to protect deliverability and scale volume without burning a single sending address. No manual scheduling required.
Sequences and Drip Campaigns
Build multi-step email sequences with conditions, delays, and branching logic. Welcome flows, onboarding drips, and re-engagement campaigns all run on the same builder.
One-Time Flat Pricing
Pay €89 once. No monthly fees, no per-contact tiers, no price increases as your list grows. Whether you have 500 or 500,000 subscribers, the cost is the same: done.
Full Deliverability Control
Sending reputation, IP addresses, authentication records, and SMTP credentials all belong to you. Diagnose and fix deliverability issues directly rather than waiting on platform support.
